I
Intervention
Ultra-high-density mapping with multielectrode catheters for substrate-based ablation
O
Outcome
Accurate definition of sites critical for re-entry and validation of late potential abolishment
Ultra-high-density multielectrode mapping may improve the accuracy and efficiency of substrate-based ablation for unmappable ventricular tachycardia in post-myocardial infarction patients.
Limitations
- Large series are necessary to definitively assess the potential role of multielectrode mapping as a guide for the substrate ablation approach
